This invention relates to a collapsible W111- dow frame, the object being to provide an improved construction wherein a window frame is presented having the usual appearance but with theparts so constructed that the partingstripsmay be easily moved to one side, so that the window sashes maybe swung inwardly or'outw'ardly, as desired, for cleaningthe window pane or for'other purposes. V

Another object of the invention is to provide a collapsible window framewherein the parting strips are hingedly mounted at the top and associated'with means at the bottom for swinging them in and out, so that they may be moved to a functioning or non-functioning position. y Y I 1 An additional object is to provide in a window frame means for guiding 'a weight used in connection with thesashes, the same being associated with a closure and lock lure 1 approximately on the line,2 2;-'

The frame 1 on each side is provided with inner and. outer members 6 and i chamberthe respective weights move.-' 0; v

posite the member 8" are arranged inner side .members 10 and 11 separated by the respec-V tive parting strips 12, 13 and "14. Only one side of the window frame and associated partshavebeen shown, but it is to be understood that the same structure is provided on the opposite side. The sidemember 11 is provided with a pulley wheel 15 of'a construction that isinco'mmon use'today. The side member 10 is likewise provided with a similar structure and the respective pulleys are supplied with cords 16 of any desired 'kind, said'cords extending downwardly so that theco'rd associatedwith' member 10 is connected with sash 2, while the cord 16 assooiated with member 11 is connected to sash 3, as shown in Figures. This cord is also 'connectedto aweight '17 any suitable man'- ner; Sash 3'is providedwith a resilient strip 18 securedby the screw'or other means to thesash 3 at 19. andpositioned'to fiexlin the font-away portion 20. This strip-is provided with a turned-over bifurcated end 21 which accommodates the end ofthe1c-0rd-l6,so

that the knot'22 will engage the bifurcated end 21 and thereby connect' the' cord'and weight with the sash to counterbalance the weight ofthe sash., This construction-is substantially the usual construction now on: the market, except for the'particular construction of the strip 18 with its bifurcated end when the sash 3 is to be removed the knot is swung outwardly and awa'yfrom end21 and then moved to engage the bifurcatedend 23 of a locking bolt 24c shown: particularly in s Figures 7 to 9. The bolt'24t is slidable and .21. The knot22when-inoperative posi tion is arranged as shown in Figureft', but

'eXtensi0n 27 when the bolt is to be held in i a locked position. "Bolt24 is carried by a fitting 28 andis adapted to 'Inove upwardly and downwardly. When movmg downwardly as shown in Figure 7, the bolt is forced through an apertured fitting 29 and then rotated until the bifurcated end 23 is in extension or notch 27. Bolt 24 is provided with a lug which slides through a suitable groove 31 in fitting 29 as the bolt moves downwardly, and when the bolt is turned for end 23 to fit into notch 27 extension 30 will move to apoint beneath the fitting 29 but out of alignment with the groove 31. This will lock the bolt against accidental movement. The fitting 29 is carried by the cover plate or door 32 which is swingably supported by the hinge 33. A similar structure is provided for the member 10, as shown in Figure 2. Whenever it should be desired to remove the weight 17 door 32 is opened and the weight removed, and after the same has been replaced the door may be closed and locked by bolt 24. It will, therefore, be noted that the bolt 24 acts in the double capacity of a bolt or lock for holding door 32 closed and as an anchor for receiving knot 22 in the cord 16 for holding the cord and weight in a desired position while the sash is removed. If this arrangement were not provided or some similar arrange ment. it would be necessary to tie an article to the end of cords 16 or to form the same into a big knot so that the end would not pass the pulley 15.

The weight 17, as shown in Figure 4,; is guided by a square tube- 34 and by a-substantially U-shaped guide 35. A similar structure is provided for member 10, wherebythe respective weights willbe properly guided and will have a portion thereof always within one of the guides. A- bracket or other suitable support 36 is provided near the bottom of guide so as to prevent the weight from dropping downwardly beyond a certain point in case the cord 16 should break. This will protect the bar 37 and tube-37 (Figure 6) and associated part-s against being injured. As shown particularly in Figure 6, bar or rod 36 isconnected with links 38 and 39. .Link 38 carries a shaft 40 rotatably mounted at one end ina bearing bushing 41. Link 39 is rigidly secured to a socket member 42 which is rotatably mounted in bushing 43. Socket 42 is preferably square or some other irregular shape so as to receive a key 44,

whereby link 39 may be moved and power transmitted to shaft or bar 37 and associated parts for swinging the same as indicated in dotted lines in Figure 4. The rod-or bar 37 extends through slots 45 and 46 formed in the'end sections 47 and 48 of the parting strips 12 and 13. Sections 47 and 48 are con nected by a rear section'49, as shown in Figure 3, so that the two parting strips are rigidly connected together and swing back and forth as a unit. The upper end of each of these strips is provided with a reinforcement 50, and through this reinforcement and the strips are formed apertures 51 adapted to receive the pivotal pin 52, whereby the parting strips may be swung back and forth. Ordinarily, the parting strips are arranged as shown in Figures 4 and 5, but when the key 44 is used and these strips are swung inwardly members 12 and 13 will move back until their" outer edges will be substantially flush with members 10 and 11. This will free the window sashes so that they may be removed or swung out of the way, as preferred. In this way the parting strips may be easily moved out of the way to free the window sashes and likewise they may be quickly and easily swung back into operative position so as to hold the sashes in their proper places. It will be noted that the parting strips, or at least, the two inner parting strips are easily moved into operative posi tion and easily moved to an inoperative po sition. It will also be noted that the cords 16 are removably connected with the sashes and are so formed as to readily interlock with the bifurcated end 23 of lock 24. These different structures are associated together so that the window frame sash and associated parts will have substantially the usual appearance of a device of this kind, but presenting these special features in such a manner that the sashes may be quickly removed while holding the cords and other parts in place.

What I claim is 1. A window of the character described. including a pair of swinging parting strips. a sash cord and weight. means for rem ovably connecting said cord with a. sash, a hingedly mounted door forming part of said frame. and a lock mechanism for locking said door normally closed said lock mechanism including a swinging and sliding bolt. said bolt having a portion acting as a. lock and a portion acting as a handle, said handle be ing bifurcated and positioned to receive the end of said sash cord when the same has been removed from said sash; whereby the cord will not accidentally move to a position within the frame.

2; A window frame of the character described, including means forming a weight passageway. said means including a do r arranged at the bottom of the frame. whereby access may be had to said passageway at the lower end. and a reciprocating and rotatable bolt acting whenin one position to locksaid door closed and when in a second position as anchoring means for a sash cord.
